摘要：We study the electromagnetic field production during preheating after hybrid inflation in a model
with the field content of the Standard Model, coupled to a singlet inflaton. We find that very
soon after symmetry breaking our system enters a regime of kinetic turbulence, characterized by
a self-similar behaviour of the energy spectra and a power-like dependence on time of the inflaton
and Higgs field variances. We still have to check that this gives rise to a magnetic magnetic
field correlated over large scales (comparable to the horizon), and that it remains correlated for a
sufficiently long time.
